PAPER-FEEDING APPARATUS FOR TYPEWRITERS.

Application filedAueust 25, 1921. Serial No. 495,277.

To all whom it may concern:

Be it known thatl, WILLIAM CHARLES AVERY, a citizen of the United, States, and

a resident of Honolulu, Territory of Ha wail, have invented certain new and useful Improvements in Paper-Feeding Apparatus for Typewriters, of which the following is a specification. I 4

My invention relates. 'to apparatus for feeding sheets of paper to a typewriter, and my invention contemplates certain new and useful improvements in the apparatus as embodied in my Patent No. 1,373,700; issued April 5, 1921. I

The purpose of my present-invention is the provision of a paper feeding-apparatus in which the paper containing trays or magazines are disposed perpendicularly and so arranged as to provide an extremely compact apparatus, and one which is simple in construction and operation.

It is also a purpose of my invention to provide a paper feeding apparatus having papercontaining magazines which are pivotally supported to insure of the proper feeding of the papers from the magazine, and which are vertically adjustable to accommodate sheets of paper of different-lengths and to so support the sheets that they will properly co.- operatewith the feed rollers in effecting the feedin of the sheetsto the typewriter.

I wi I describe one form of paper feeding apparatus embodying my invention, and will then point out the novel features thereof in claims.

In the accompanyin drawings:

Referring specifically to the drawings and particularly to Figures 1' and 4-, P designates the platen of a standard form of typewriter which is shown as arranged in advance of. the paper feeding. apparatus embodying my} invention. The apparatus in the present instance comprises a frame Fof U-shaped formation and including a base port on.v 15

are provided at their upper ends with vertically arranged slots 17 and 17, the upper.

ends of which are in communication with the upper edge of the frame so as to permit of the insertion'of adjusting, devices therein as will be described hereinafter. Supported for swinging movement between the sides 16 and 16 are a plurality of magazines or trays designated at M, M and M respectively, although it is to be understood that any so and side portions 16 and16 As shown in Figures 1 and 4:, the side portions 16 and 16'" number of 'inagazines can be provided de- I pending upon the number of sheets desired to be fed to the typewriter. The upper ends of the magazines constitute the delivery ends from which the sheets of paper are adapted to be withdrawn. These delivery ends are provided with upwardly extending guide flanges 141 designed to guide the sheets of paper into contact with feed rollers. The magazines are supported in vertical position by means of screws 18 horizontally arand 17 and se curedin any one of a plurality of openings 19 formed in 'a flange 20 secured to or formed integral with each of the magazines-M, or M. As shown in Figure 11, each screw 18 is provided with nuts 21 arranged upon the shankof the screw to embrace the flange 20 and to secure the screw in horizontal position so that its free end will project through the corresponding slot 17 or 17 to a point exteriorly of the frame. The projecting end of each screw is adapted to be enaged by an adjusting screw 22 threadedly tted in a projection 23 preferab1y formed integral with the side portions 16 or 16 of the frame Fand disposed at the lower end of the slot 17 or 17 The arrangement of the screw 22 is such that its free end engages the projecting end of the screw 18 so thatby' adjusting the same vertically within the projection 23, a correspondin adjustment of the screw. 18 is effected. id y simultaneously adjusting-the companion screws 22 of any one magazine M, M 01'' M it will be clear that the corresponding screws 18 are likewise adjusted to effect a vertical adjustment of the corresponding magazine.

'The upper end of the frame F supports and'is adapted to be spanned by a feeding device which, in the present instance, comprises a pair of plates 24: secured in spaced relation by means of rods 25 and forming in efi'ect a continuation of the side portions 16 and 16 of the frame. This feeding device is supported for swinging movement to spanning and non-spanning positions with respect to the frame by means'of'hinges 26 secured to the upper edge of the frame and to the lower edge of one of the plates 24 so that the device as a. whole can be swung from the spanning position shown inFigure 3 to a -'non-spanning position as indicated in dash lines in Figure 3.

Ihe 'feedingdevice also'includes a pluralityof shafts S, S and S journa-le'd in the plate 24 and upon each of which are secured a plurality of feeding units designated at N. "As shown'in Figure 4:, the shafts are arran ed in progressively ascending horizontal planes, and the feeding units of each shaft occupy a correspondingplane. As

shown in Figure 7 each feeding unit comprises a sleeve 27 fixed to the shaft by means of a screw 28 and having secured thereto a pair of feed rollers 29, each of which is constructed of rubber and provided with radially extending teeth in the same manner as is the rollers embodied in my patent here in referred to. In the present instance I have provided three shafts one for each of the magazines, and three feeding units on eachof the 'shafts, it being understood. however, that any number of feeding units may be provided and any number of rollers with each feeding unit.

The several shafts areadapted'to, be sithe typewriter.

multaneously rotated in effecting actuation of the feeding rollers for simultaneously feeding the sheets of paper from the several magazines, and to this end I provide one and the same end of the several shifts with pinions 30, 30*, and 30 for the shafts S, S and S respectively. The pinions 30 and 30 mesh with a driving gear 31 slidably fitted in a stub'axle 32 secured in the corresponding plate 24. The gear 31 has fixed thereto another gear 33 which meshes with a gear 30 of the shaft S. The gear 31 is provided with an operating crank 34 by means of which gears 31 and 330m be rotated, to effect actuation of the pinions and rotation of the shafts. As previously stated, the gear 31 is mounted for sliding movement on the axle 32, the purpose of this arrangement being to allow of the moving of any of the gears 81 out of mesh with the pinions and thus permitting of the independent or simultaneous actuation of any of the shafts. Any one shaft is adapted to be manually operated independently of the other shafts by means of a crank 35 fixedto the opposite end of the shaft from that end to which the ends with the plates 24 and spanning the space therebetween These'lips are so associated with the feeding units as to guide the sheets of paper into contacting relation with the feed rollers and to cooperate with the latter in effecting the feeding of the sheets from the several magazines to the platen of As shown in Figures 4 and 8, each maga- -zine is provided'at its lower end with a follower 37 movably fitted within the magazine and adapted to be manually elevated or lowered through the medium of a pair of. screws 38 threadedly fitted within the bottom wall of the magazine and provided with heads 39 rotatably fitted in. sockets 40 formed on the follower 37. From this arrangement it will be'seen that by rotating, the screws in one'directien or the other, a vertical adjustment of the follower is elfected. The followersjare designed for the purpose of supporting the sheets of paper within the magazine and irrespective of the K length of the sheets. This facilitates the feeding of the sheets by the feed rollers as by an adjustment of the followers, the sheets can be supported so that their upper ends are disposed between the feed rollers and-the guide lips 36 so that when the former are rotated they will effect vertical feeding of the sheets from the magazines.

As shown in Figuif'e 10. one plate 2% of the feeding device "gf iijrovided with orifices e1 having restricted mouths through which latch pins 42ers ada'ptedto pass into the orifices for temporaril y securing the feeding device in proper position upon the frame. The latch pins 42 are secured'within and in spanning relation to pairs-of blocks 43 secured to the upper edges of the portion 16 of the frame F So that when the feedingdevice is moved into spanning po' sition upon the frame, the pins will pass into the orifices 41 which, by virtue of the restricted mouths, temporarily maintain the device in spanning position.

In operation, the apparatus is arranged in vertical position and at the rear of. the typewriter in the manner clearly shown in Figuresl and 4,- with the delivery ends of the magazines disposed directly below the' feeding units so that the upper ends of the sheets of paper lie contiguous to the flanges 1 4: with the latter disposed adjacent the rear side of the feed rollers as is clearly shown in Figures. The magazine M is adapted tocontain the original sheets of paper, the magazine M containing the carbon sheets, and the -magazine M the copy sheets. lVith the gears 31 and 33 in mesh with the pinions of the several shafts S and S it will be clear that upon rotation of the gears, the several feeding units will.

\ be rotated in a counter-clockwise direction as when viewed in Figure 4 to engage the forwar dmost sheet of each magazlne and feed the same upwardly, outwardly and forwardly under the action of the guiding lips to the platen of the typewriter. It is to be understood that the flanges 14 cooper-.

ate with the guiding lips 36 in directing the sheets of paper into contact with the feed rollers, the lips also coacting with the rollers so that the teeth of the latter will efi'ectively grip the sheets in feeding the same from the magazine. \Vhen the several sheets of paper have been fed far enough to be engaged by the platen. the operator then rotates the platen in the usual manner causing the further feeding of the sheets into proper position upon the platen. Prior to this manual feeding operation, the gears 31 and 33 are moved out of mesh with the pinions so that the independent rotation. of the shafts and feeding units can be effected in order that the proper feeding of the sheets of paper to the platen can take place. This construction also allows of the operation of two of the feeding unitsto feed a carbon sheet and a paper sheet when morethan one copy of a letter is desired. By virtue of the fact that the magazines are pivotally "sustained by means of the screws 18, it will frame and including understood that various changes and m'odiiications maybe made herein without departing fromthe spirit of the invention or the spirit and scope of the appended claims.

\Vhat I claim is g 1'. paper feeding apparatus for typewriters comprising a frame. a vertical magazine supported by the frame, means for adjusting the magazinevertically and a feed-' ing mechanism swingingly supported upon the frame for movement to and from position to withdraw sheets of paper from the magazine.
